[2] In his Chronique latine he claims to have worked on a chronicle of the reign of Charles VI from 1407, assisting Michel Pintoin.
He was first mentioned in the capitular records of the Abbey of Saint-Denis in 1430 as the prévôt of la Garenne.
[3] In 1441 Chartier and three other officials were assigned by the king to the administration of the temporal affairs of the Abbey.
In 1450 he accompanied Charles VII on a campaign to Normandy to besiege the English-held Harfleur.
[1] He finished the chronicle of Charles VI, known as Historia Karoli Sexti Francorum regis, after Pintoin's death c. 1420.
